In another aspect, disclosed is an apparatus for loading particulate material into a container, the apparatus comprising a primary chute having an outlet, a trim chute engaged with the primary chute and moveable with respect to the primary chute wherein movement of the trim chute with respect to the primary chute adjusts flow of material into the container.

In some forms, the trim chute is engaged with the primary chute by at least one trim chute extendable arm, the trim chute extendable arm effecting movement of the trim chute with respect to the primary chute.

In some forms, the movement of the trim chute with respect to the primary chute is an angular movement, adjusting the angle of the trim chute.

In some forms the trim chute includes an outlet that feeds directly into the container.

In some forms the container comprises a rail wagon.

In some forms the primary chute comprises a fixed chute through which particulate material is received in

16763275_1 (GHMatters) P99893.AU.3 12/11/20 use, and a swing chute adapted to extend from the fixed chute.

In some forms the swing chute is angularly moveable with respect to the fixed chute.

In some forms the swing chute is moveable to adopt a raised position when not in use.

In some forms the apparatus further comprises a moveable barrier engaged with the primary chute and moveable to adopt a closed configuration wherein the outlet is obstructed and an open configuration.

In some forms, the barrier comprises a single clamshell bucket.

In some forms, the bucket is engaged with the primary chute by means of at least one barrier hydraulic arm which effects movement of the bucket between its closed and open configurations.

In some forms, extension of the barrier hydraulic arm causes the bucket to adopt the open configuration.

Referring to Figure 1, disclosed is a chute assembly 1 for loading particulate material into a container 2. In the illustrated form the container is a rail wagon.

In the illustrated form, the chute assembly 1 comprises a chute body 4 extending from a gateframe 5. The chute body 4 comprises a fixed chute 6 located proximal the gateframe 5 and into which material initially flows. A swing chute 8 is engaged with the fixed chute 6 by means of a pin 9. A swing chute hydraulic arm 11 engages the swing chute 8 and the gateframe 5.

16763275_1 (GHMatters) P99893.AU.3 12/11/20

The swing chute 8 is moveable from the lowered position illustrated in Figure 1 into a raised position which is best shown in Figure 2. Movement of the hydraulic arm 11 moves the swing chute from the lowered position into the raised position through rotation about pin 9.

In the illustrated form, a barrier in the form of a single clamshell bucket 12 is located in and engaged with the swing chute 8. The bucket is rotatable about axis 14 to move the bucket between the closed configuration shown in Figure 1 and an open configuration. A bucket hydraulic arm 15 effects movement of the bucket 12 between its closed and open positions.

In the illustrated form, guillotine gates 26 block particulate material from the chute in a closed position and open to allow material through.

In its closed position, as shown in Figure 1, the clamshell bucket blocks flow of particulate material from the swing chute 8.

A trim chute 18 is engaged with the swing chute 8 at pin 19. A trim chute hydraulic arm 20 also engages the trim chute 18 and attaches it with the swing chute 8. The trim chute 18 is moveable with respect to the swing chute 8 about pin 19 by movement of an extendable arm in the form of trim chute hydraulic arm 20.

While the illustrated form shows the adjustable trim chute in use with a fixed chute and swing chute system, the trim chute can be utilized with other chutes such as fixed chutes and lowering telescopic chutes with either single or twin guillotine gates. Most coal loaders are a guillotine style with a lowering telescopic or cross traversing chute which floods and empties with each wagon. The chutes either side traverse or raise to clear the

16763275_1 (GHMatters) P99893.AU.3 12/11/20 locomotives.

Adjustment of the trim chute is performed using a data system into which weight data is fed from scales on outgoing rails which measure the bogie, axle, wheel and front/rear wagon masses.

Referring now to Figure 2, the swing chute 8 is rotatable with respect to the fixed chute 6 in order to move the swing chute 8 into its raised position that is shown in Figure 2. In its raised position the chute assembly 1 is out of the way of a wagon 2 moving through when loaded. A lock hook or latch 24 is attached to the gateframe 5 and secures the swing chute 8 in the raised position when the system is not in use. The lock hook or latch 24 can be either a single latch or a double latch in which case one is located on each side of the gateframe 5. This is operated by spring extended cylinders. The lock is required as when the system is left unused for long periods, the latch prevents the chute creeping down which could cause an interaction with a locomotive or loaded wagons or rail maintenance equipment travelling through.

Referring now to Figures 3 and 4, the trim chute 18 is angularly moveable with respect to the swing chute 8 and fixed chute 6. In the illustrated form, movement of the trim chute 18 is effected by movement of the trim chute hydraulic arm 20, however alternative dynamic '0 configurations would allow similar movement of the trim chute 18. For example, telescoping arms such as electric or alternatively powered linear actuators or other extendable arms could be utilised.

The trim chute 18 illustrated in Figures 1 to 4 has at least two opposed side wall portions and a front wall portion that generally surround a trim chute outlet face allowing particulate material to flow, in operational use, from a primary chute arrangement consisting of the fixed chute 6 and the swing chute 8, into the container 2. As shown in Figure 3, in the lowered position, the trim chute 18 is positioned whereby the front wall portion engages deposited particulate material in the container 2 to provide a container load profile 22 of the particulate material 23. The deposited particulate material 23 has a load profile 22 of a specified height above.

the container 2. As shown in Figure 4, in the raised position the height of the container load profile 22 above the container 2 is greater.

Figures 5 and 6 show end views of the container load profiles of Figures 3 and 4.

The variable trim system allows for full flow through the vertical areas (y axis) of the chutes and controls the load level (trim) along the horizontal plane (x axis). The adjustable trim system has been designed to provide a variable y axis load height profile.

Referring now to Figures 7 through 11, variations in load height throughout the full profile of the container are enabled by the adjustable trim chute 18. This dynamic adjustment provides loaded volume and subsequent mass variations from front to rear of the wagon while the wagon loads through feedback provided without needing to alter the opening distances.

In Figure 7, the container load profile 22 is level and relatively low. In Figure 8, the container load profile 22 is level and is high. This variation is produced by adjusting the trim chute 18 from a lowered setting to a raised setting.

Higher wagon load profiles result in an increase of transported particulate material. This results in cost and efficiency savings.

In Figures 9 through 11, the container load profile varies across the load. This variation is produced by varying the angle of the trim chute while the loading is occurring.

In Figure 9, the load profile 22 is tapered from

16763275_1 (GHMatters) P99893.AU.3 12/11/20 front to rear, as the trim chute 18 is lowered during filling. This is useful when a wagon weighs in with the rear bogies as being underweight with the bulk load longitudinal profile being flat and the front bogies weigh in as correct. The PLC records the wagon weight disparity input data and calculates the correction requirement. Trim height and opening distance for the front of the subsequent wagon remains "as is", while the load will taper up from front to rear.

In Figure 10, the load profile 22 is raised from front to rear. In circumstances wherein the wagon weighs in with the front bogies as being underweight with the bulk load longitudinal profile being flat this profile would be desirable and the system can correct for it.

In Figure 11, the container load profile 22 peaks in the centre.

The flat, tapered or peaked load over length of the wagon correct for weight imbalances from track scale data input received from previous wagons. The load can be automatically adjusted from the plc and corrected from track scale data input received from previous wagons.

Referring now to Figures 12 and 13, the trim chute 18 can be utilised with a fixed chute system.

Figure 12 shows the trim chute 18 in a lowered configuration. The trim chute 18 is engaged with the gateframe 5 by means of at least one hydraulic arm 25. The hydraulic arm engages the trim chute and extends to move the trim chute 18 into the lowered configuration. In this embodiment guillotine gates 26 are also shown in the open position.

Figure 13 shows the trim chute 18 in a raised

16763275_1 (GHMatters) P99893.AU.3 12/11/20 configuration. The trim chute 18 is engaged with the gateframe 5 by means of at least one hydraulic arm 25. The hydraulic arm engages the trim chute and is retracted to move the trim chute 18 into the lowered configuration.

The adjustment of the trim chute can be adapted to reduce and prevent initial front overspill of the wagons by lowering the trim chute upon wagon presentation and then raising it to the required level once the initial surge/flood has completed. Dependent upon requirements this can be integrated into the PLC program to operate with each wagon.

The hydraulic supply for the adjustable or dynamic trim chute is generally sourced from the original system chute pressure supply, main return and drain lines tee connections. The small volume and power required to operate the adjustable trim system is minimal and has minimal or no effect on the functioning of the OEM designed main system

Control valving and components are incorporated in a purpose designed stand alone manifold assembly mounted to the underside of or near the gateframe

The trim system is able to be isolated from the main hydraulic system by lockable isolation valves. Dynamic trim system operating maximum speed is controlled by a flow control valve. In most systems a failsafe (emergency shutdown) valve is energized throughout the loading process (for the train duration) unless an emergency shutdown occurs.

The failsafe valve is identical to the main hydraulic system failsafe emergency shutdown valve and energisation operates in parallel.

16763275_1 (GHMatters) P99893.AU.3 12/11/20

A double solenoid valve raises, lowers or maintains the chute in the desired position upon being energized or de-energised.

The system is designed so that irrespective of whatever signal at the time is for raise, lower or maintain position, the failsafe operation will be prioritized for the emergency shutdown and the normal control signal will be negated.

While the disclosure is directed toward filling rail wagon containers with particulate material, such as iron ore, it will be clear that alternative materials and alternative container settings may be utilised in line with the disclosure of the application. The chute system can also be utilised in typical truck loader operation and in coal chute train loading among other particulate material loading arrangements.

In other alternative arrangements, the trim chute can be applied to a fixed chute system and installed in a blade shape rotating on a mounted hinge at the rear of the chute. The trim arrangement can be either a single or twin actuator operated. Existing designs that are not hydraulically operated can be installed with electric linear actuators for trim adjustment. To provide sufficient clearance from the clamshell bucket, trim chute width can be altered either as a modification to the existing system or a new trim chute designed allowing for additional clearance.
